I have a speedball installed and no longer have the installation manual. Which smaller speedball board is for the right channel? Thanks in advance and happy Memorial Day

This actually isn't particularly important, as they are both the same.  In the manual, the "A" board goes next to the headphone jack.

I know they are the same - I have a right channel issue. I want to know which board to focus on- right or left

I have a tight channel issue. I want to know which board to focus on- right or left
If you would like a second set of eyes to confirm your determination that the right C4S board is the problem, do feel free to post your voltages and symptoms.

I can't find my speedball build manual- I would like to get another copy so I can check things and post my voltages

Fwiw one led on the left board is out- some LEDs took a bit to illuminate

All I get out of the right channel is hum

Speedball voltages are about the same as the voltages in the stock build.
